By the break, the Tigers had also run more than three times as many metres as Manly, had 70 more runs and been forced to make 103 fewer tackles.

An indication of the Tigers' dominance was that after 20 minutes, prop Ben Matulino had 10 runs for 105m, while opposing forward Addin Fonua-Blake had none at all.

Marshall turns back the clock against Manly

Brooks was at the heart of it all. He set up their first two with a kick close to the line and then a slick pass from his own half before he landed the knockout blow with his own try from dummy-half just before the break.

"We go in at 14-0 we're still a chance but to concede one from dummy-half is just not on," Manly coach Trent Barrett said.

"It was diabolical on a number of fronts. To have about 20 per cent of the ball is a record since I've been coaching."

Marshall also showed signs of his best, running onto a Brooks ball to cross in the 33rd minute then pulling out his famous sidestep to score minutes into the second half before Manly nabbed two consolation tries.

The Tigers' embarrassment of the hosts went far beyond the scoreboard as the Sea Eagles were booed off at halftime by a crowd of 15,546.

At one stage, Marshall bombed the ball high into the sun before it bounced back into the hands of Naiqama.

Naiqama then got the ball back to Marshall, who hoisted it high in the air again before Tom Trbojevic caught it and was forced into touch to sum up Manly's horrid day.
